I have Windows Vista or Windows 7, and everytime I start my computer I have to give the Clean Access Agent permission to run, is this normal?
Yes, this is due to an enhanced security feature present in Windows Vista and Windows 7 called User Access Control (UAC). Because Clean Access accesses areas of your computer that are part of the operating system and needs access to your network settings, it must run with elevated permissions. If you do not give Clean Access Agent permission to run, you will not be able to access the network.
